This is my first post on the VR forum. I used to be involved in VR when the first Oculus rift was crowd funded then lost interests until MSFS 2020. I recently bought an HP Reverb G2 and noticed a few crashes that make the G2 not really usable. When it works, usually it is sort of smooth but the big drawback is that it will crash while in VR mode. First time I tried the VR I selected the activities/bush trips. I managed to fly 1 hour then it crashed. Symptoms were: video frozen in the helmet (and desktop if I liftd my helmet), then blackout with sound still on in the helmet. Eventually after a few minutes, MSFS will crash then it will return to the desktop and I’ll get an AMD driver message about a driver time out. When flying, it was smooth and I did not tinker a lot with the VR settings (in fact I did not realise that under “graphics” you could switch to VR so the graphics settings were at their defaults values). Following that I started to tweak the settings in graphic to make sure that they were not stressing my video card (5600 XT), installed openxr dev tools, found some recommendations about adding “tdrdelay” in one of the windows registry to give some extra time to the drivers but all that contributed to have more stuttering in VR. Also disabled “Game mode” in windows, check that Hardware GPU acceleration in windows was disabled (did not have this option) and also that the MSFS executable had its “disabled full screen optimisation” as per one of the youtube video).
So in the end I removed the openxr dev tool but left game mode off, the tdrdelay and the graphic settings as they were. No more stuttering in VR but still crashing. Except that this time I don’t have the AMD driver time out message. So not sure if it is the tdrdelay that is fixing this issue but the crash is still there and I don’t know what it is since there is no message. And the crashes are getting more and more frequent. Now not 5 minutes within a flight it will crash. One crash was so bad that it crashes the whole system. But the big BUT is that i can fly the same flight plan not in VR and I have no issue. I could resume the bush trip or the flight that crashed within 5 minutes, fly for another hour in non VR mode and everything was fine. I am at the point where I don’t know where to look so hopefully someone can help. I could remove the tdrdelay in the registry and see if next time it crashes the AMD driver time out message reappear just that I know at least this tweak is fixing one issue.
Note also that the video card is not overclocked and I am using the latest AMD drivers (updated yesterday) and windows is up to date as well.
My config is:
Gigabyte Z490 Vision D motherboard
i9 10700k stock speed
Gigabyte 5600 XT 6GB stock speed
64 GB 3600Mhz (stock speed)
HP Reverb G2 connected to video card display port and usb-c at the back of motherboard
Thanks a lot
